VALVE CONNECTION FOB GAS-PURIFIERS.

SPECIFICATION forming part of Letters Patent No. 774,911, dated November15, 1904.

Application filed July 25, 1904.

To a, w/wm, if; nuty concern.

Be it known that 1, JOHN S. DE HART, Jr., a citizen of the UnitedStates, residing at East Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in ValveConnections for Gas-Purifiers, of which the following is aspecification.

My invention relates to an improved arrangement of mains, branch pipes,and valve connections for gas-purifiers whereby a plurality of boxes maybe operated in sequence, the gas made to enter any one of the boxesfirst and then pass through the others or cut out any one of the boxesfrom the main system when required to recharge with fresh purifyingmaterial or repair them without interrupting the use of the remainingboxes.

The objects of myinvention are, first, to construct a system of pipesand valve connections whereby a minimum length of piping and number ofvalves are used in order to install or operate a plurality of boxes of agas-purifier; second, to arrange pipes, valves, and connections so thatany one of the boxes may be cut out or the sequence of operation bequickly and readily changed with the least amount of labor and cost ofinstallation; third, to arrange a system of pipe connections and valvesin one aisle of a purifyinghouse having a plurality of boxes in orderthat the remaining aisles be as small as possible and the head-roombelow the purifier be free from all obstructions.

The invention consists of features and relative arrangement ofpurifier-boxes, pipe, and valve connections, which will be hereinaftermore fully described, and particularly pointed out in the appendedclaims.

In the drawings, in which similar reference characters indicate the sameparts in both figures, Figure 1 is a top plan view of my system ofpiping and valve connections applied to a purifier consisting of fourboxes with the covers removed. Fig. 2 is an end elevation at the line 0w of Fig. 1 looking in the direction indicated by the arrows.

Referring to the drawings, B, B B and Serial No. 217,991. (No model) l Brepresent four purifier-boxes having their covers removed and supportedside by side, with an open space between them sufficiently wide so as topermit the system of pipes and valve connections to be placed therein.As is usual in the construction of the purifiers of gas plants, theboxes are supported upon an elevated flooring F, having uprights f, asindicated in Fig. 2, and which has not been fully shown, since it formsno part of the present invention and is readily understood by thoseskilled in the art of installing gasmanufacturing plants.

The purifier-boxes B, B B and B*, which are referred to and numbered inthe order "with which the gas passes through them, are provided withinlets I. l l and 1* and outlets O, O O and O, respectively.

G is one of the trunk-lines placed in the space between the boxes andforms the main inlet for the gas. Pis the other trunkline, which ispreferably located directly under the main inlet Or (see Fig. 2) andforms the main outlet. The inlets of the boxes are each connected to theinterior of similarly-constructed valve-casings V, V V and V, and theoutlets to the interior of valve-casings E, E E and-11*, respectively.The interior of each of the inlet-valve casings V, V V, and V isconnected on one side by short branch connecting the other side andinterior of the outlet valve casing E with the other side and interiorof the inlet-valve casing V and O* is a pipe connection similar to Oconnecting the other side and interior of the outletvalve casing E withthe interior of inlet-valve casing V pipes 6, 6 I2 and b, respectively,to the main Each oi" the inlet-valve casings V, V V and V is providedwith two valves, which are shown in dotted lines and numbered 1, 12, 3,1, 6, 7, 9, and 10, and the outlet-valve casings E, E E and E areprovided with one valve only and are marked 2, 5, 8, and 11. Valves 1,1, 7, and 10 control the branch connections 7), 7/ 5, and b of the maininlet with the interior of inlet-valve casings V, V, V and V,respectively, while valves 2, 5, 8, and 11 control the branchconnections a, e, a, and a with the main outlet P. Valves 3, 6, 9, and12 control the pipe connections C, 0 I, and C with the inlet and outletvalve casings, as will be clearly seen and understood from Fig. 1 of thedrawings. The valves indicated in the different valve-casings may be ofany common and well-known gate, disk, or other suitable "form of valvefound best adapted t'or the carrying out of the invention and may beoperated by a hand-wheel or le-- ver 7t, indicated in the drawings andforming no part of the present invention. It is also to be understoodthat other forms of inlet and outlet valve casings "from that showncould be adopted without departing from the herein-disclosed invention.V

The operation oi the invention is as follows: 11 it is desired to usethe four boxes B, B, B and B" of the purifier, the gates or valves 1, 3,6, 9, and 11 are opened and valves 2, 1, 5, 7, 8, 10, and 12 are closed,when the path of the gas which enters is in the direction of arrow (L tothe main inlet Gr, thence through in the following order the parts 7)V"l B O E! G/ 72 12 1&2 02 E2 (/2 V3 13 B3 0315:; N3 71 1-1 B O E c" tomain outlet P in the direction of arrow (1. If it is desired to cut outbox B, the valves are in the same position as above, except valves 1 and3 are closed and 1 is opened, the gas then passing through boxes B, B,and B". \Vhen box B is ready to be thrown into service again, it entersat the end of the sequence by opening valve 12 and admitting gas frombox B", through the connection C, after the valve 11 is closed, shuttingofl box B from the main outlet P. If it is desired to cut out box B,valves 1, 3, 4c, 5, 6, 8, 10, and 11 are closed and valves 2, 7, 9, and12 are open. The gas then passes, by means of the main gas-inlet G,directly to the inlet of box B thence through B", and then through boxB, and the valve 3 being closed and valve 2 open permits the gas to passinto the main gas-outlet P. When it is desired to cut out box B, thevalves 1, 2, 1, 6, 7, 8, 9, and 11 are closed and valves 3, 5, 10, and12 are open. The gas then passes, by

means of the main gas-inlet, directly to the inlet of box B", thenpasses through box B, and then through box B and the valve 6 beingclosed and valve 5 open the gas passesto the main gas-outlet P. Box Bmay be cut out in a similar manner by having the gas first enter box B,then pass through box B andfinally box B to the main gas-outlet. Thissame rotation and operation of valves may be continued indefinitely,and, if so desired, more than one box may be cut out at any one time.

From the foregoing detailed description of the invention and the mode ofoperating the same it will be clearly seen that I have devised a systemof mains, branch pipes, and valve connections in which the objects setout in the statement of invention are fully attained and efficientlycarried out.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is as follows:

1. A purifier for gas or the like, comprising a plurality ofpurifying-boxes arranged side by side with an intervening space betweenthem and each having an inlet and an outlet, a main gas-inlet and a maingas-outlet located in the intervening space, an inlet-valve chamberconnected to and for each of the inlets of the boxes, an outlet-valvechamber connected to and for each of t the outlets of the boxes, branchpipes connecting one side and interior of each of the inlet-valvechambers with the main gas-inlet, branch pipes connecting one side andinterior of each of the outlet-valve chambers with the main gas-outlet,a pipe connecting the other side and interior of each outlet-valvechamber with the other side and interior of the inlet-valve chamber ofthe next box in the sequence, two controlling-valves in each of theinlet-valve chambers, and a controlling-valve in each of the outletvalvechambers.

2. A purifier for gas or the like, comprising four purifyingboxesarranged side by side with an intervening space between them and eachhaving an inlet and an outlet, a main gas-inlet and a main gas-outletlocated in the interveningspace, an inlet-valve chamber connected to andfor each of the inlets of the boxes, an outlet-valve chamber connectedto and for each of the outlets of the boxes, branch pipes connecting oneside and interior of each of the inlet-valve chambers with the maingasinlet, branch pipes connecting one side and interior of each of theoutlet-valve chambers with the main gas-outlet, a pipe connecting theother side and interior of each outletvalve chamber with the other sideand interior of the inlet-valve chamber of the next box in the sequence,two controlling-valves in each of the inlet-valve chambers, and acontrollingvalve in each of the outlet-valve chambers.

In testimony whereof I afiix my signature in presence of two witnesses.
